The platens 16 areall'arranged to: have anexactly equal surface speed, and the said platens, with their presser-rolls'=-19,' act as feeding mea fornil' feed all the sheets forward. The take-- u re lers 7, which are driven through frict o'nimeans 8, arearranged to be driven at a speed sufficient to always take up the amount of sheet'fed to them-.that is; to sag,

' order to provide forwithdrawing all thelprlesser-rolls at one time from engagement 1 their respective platens, so as to put the machine in condition for removing or insertmg record and master-sheets, I have arranged ,I acam-shaft longitudinally upon the outshaft provided with cam projections 26, ar- 1 sided one of the side frames5, said camranged when the shaft is moved longitudinally to engage the arms 21 ,:-secured to the "shafts 20, which'ca-rry the resser-rolls 19,

' After the machine has run for a length of time'sufficient to pay off all ofthe record fand patte'rn sheets from the rollers 12 and 11 the drive may be stopped, the pressiar-rolls .IQffreedby manipulation of the-handle 29,

is effected by means of a rewind-shaft op:-

v eratedf-by a handle 49 or other means, said rewind-shaft having mitergear-wheels 31 in engagement with the miter gear-wheels 14 rewound upon their rollers 12 and 11. This above, mentioned; The. pattern or master sheet 23 is provided with perforations corresponding in relative position 'withthe expression markings which. it is desired to produce uponthe record-sheets Disposed beneath the first platen 16-that -is, the, -platen 16, withwhich the' said master or:

pattern" sheet engages' are a number of spring-fingers 32, said fingers mounted upon.

1 and carried by. a- .beam- 33, mounted at 3.4,

and provided with an arm 35, adapted to engage wit-hnotches in .a uadrant 36. The

Thus wheneverv a perforation in the mastersheet 23 comes opposite a spring-finger electrical connection will be made with the individual spring-finger in register with the open- 1 ing at that time, as willbe well understood. These spring-fingers are arranged in elec-* 'trical communication with 'electromagnets 3 38, arranged in the base of the machine, said i magnets 38 having armatures 39 connected by means of links 40 with rocking-bars 41. In the present example of my invention there is one eleciromagnet 38 forevery -finger i 32,- and one rocking bar 41 for every electrof magnet 38. Parallel movement of the rocking bars 41 is preferably enforced by means Each bar 41 is connected by means of suitable connections, such connections herein comprising asaddle 43,. a link 44,-and an adjustable turn-buckle 45, with the operating-arms of pivoted impression-ha1nmers 46. .Each bar 41 is connected with one such hammer for each record-sheet tobe operated upon, and while but two such record-sheets and parts for !mounted, as shown.

of links 42, upon which the said bars are supporting and operatin same are shown in the apparatus herein illustrated. it will be understood that in an actual machine provision 18 made for operatlng upon very many upon atone time, as will be well understood. The saddle 43 is preferably connected by a spring portion 47 with the bar 41, so as not only to take up shock, butalso to compensate for possible variations between the movements of the varioushammers 46 con neeted thereto. There are two rows" of hammers .46 for each record-sheet, one set mounted upon one side thereof and moving ed on the other side thereof and moves in the other directlon. This is in order to permit expression-marks to be made closer together being arranged in staggered or alternate relations wlth each other, as will, be readily un'- drawings.-

In the operation of the machine the mas l ter-sheet will cause the closing of circuit through selected fingers 32 in accordance withtheposi-tion of the openings in saidsheet, and the electromagnets .38 will be energized (from asuitable source of power) inaccorda'n'ce with the fingers 32 selected.

duce expression-marks upon the recordsheets-24 corresponding to the perforations -in the master-sheet 23. Ink-ribbons 48 beneath allof the platens 16 except the first one more sheets at one time and that any number within reasonable limits may be operated in one direction, while the other set is mountthan would be possible with only one row of hammers, the opposite rows of hammers derstood by reference "to Fig. 3 'of the ITS | This will effect movements of corresponding impresslon-hammers 46, wherewilh to protsupply the coloring material for marking the sheets when the impression-hammers 46 strike their blows. The ink-ribbons 48 may be fed gradually forward in any suitable and well-known manner.

From the foregoin it will be understood i that once a masters eet has been preparedhaving orifices corres onding to the perforation-markings desire to be pro'dueed such
